Brief Summary: This study will be a single-institutional randomized single-blinded prospectively controlled clinical trial of a single dose of Ciprofloxicin 500mg antibiotic tablet as prophylaxis at the time of office flexible cystoscopy with ureteral stent removal The control group will be no prophylaxis oral antibiotics
Detailed Description: This study will be a single-institutional randomized single-blinded prospectively controlled clinical trial of a single dose of Ciprofloxicin 500mg antibiotic tablet as prophylaxis at the time of office flexible cystoscopy with ureteral stent removal The control group will be no prophylaxis oral antibiotics The study will be conducted at UCSD Urology outpatient clinic and Genesis Healthcare Partners Urology outpatient clinic UCSD will be the coordinating institution

Treatment Assignment

Patients will be assigned to control or intervention arm based on a predetermined allocation sequence that will be generated by a computerized random number generator Study staff not participating in patient recruitment or procedure will manage the allocation sequence Physicians involved in urologic patient care will be blinded from the participants allocation Only study staff at the coordinating institution UCSD will have access to the full allocation sequence ie no clinical staff involved in recruiting and consenting patients for the study at UCSD or other participating institutions will have knowledge of the allocation sequence at their institution prior to enrollment of each patient To further aid allocation concealment the block size will be varied

Standard of care procedures

Patients will be identified at the time of clinic visit for cystoscopic stent removal All patients will be counseled on the American Urological Associations clinical guidelines for prophylactic antibiotic use and the varied standardization of practice patterns We will not deviate from routine care standards Patients undergoing routine ureteral stent removal within two weeks following stone treatment procedure ie Percutaneous Nephrolithotomy Ureteroscopy Retrograde Intrarenal Surgery or Extracorporal Shockwave Lithotripsy Patients that agree to participate and provide consent will be enrolled into the study receiving a randomized allocation and specific data points will be collected prospectively Patients will be consented prior to determination of prophylaxis for collection of demographic disease perioperative and postoperative data If the patient does not consent to the study the use of antibiotics will be based on the routine clinical practice of the treating urologist

Investigational portion of treatment

Patients randomized to the intervention arm will be provided a single oral dose of Ciprofloxacin 500mg at the time of stent removal Ciprofloxacin is currently indicated for the treatment of acute uncomplicated urinary tract infections Patients with fluoroquinalone allergy will receive Bactrim trimethoprimsulfamethoxazole 160800mg single dose instead of Ciprofloxacin Those patients that do develop infectious complications after stent removal will be treated empirically based on the preference of the treating physician followed by culture specific antibiotics Centeral prophylaxis randomization will take place at UCSD as the lead site using staff members not involved in patient management Randomization will occur in block randomization in block sizes of 10

Standard of care procedures Patients will have cystoscopy and stent removal performed in standard fashion without deviation from standard of care The time frame of stent removal after initial stone procedure is consistent with current standard of care If the treating physicians preference is to maintain the patients indwelling stent for longer than two weeks then the patient would not be considered for this study No patients management course will be altered for inclusion into this study

All female patients are screened with a urinary pregnancy test during the preoperative screening visit which occurs before the kidney stone surgery Any pregnant female patients will be excluded from participation in this study Post-operative instructions include refraining from sexual activity Cystoscopic stent removal is performed within 14 days of surgery

Demographic fields that will be obtained preoperatively include age race gender body mass index BMI and comorbidities including history of diabetes mellitus immunosuppression prior urinary tract infections neurogenic bladder incomplete bladder emptying Pre-operative clinical data points will include kidney stone size largest diameter as measured on coronal imaging for either kidney-ureter-bladder plain x-ray or computerized tomography and pre-operative urine culture results

Post-procedure fields will include post-void residual urine volume per bladder scan to assess emptying capability culture of urine collected during stent removal only to be treated with antibiotics if patient becomes symptomatic - per standard of care stone culture results stone analysis and stone-free status Phone call interview will occur between 7-14 days post-operatively to determine if any post-operative infectious events have occurred Any infectious symptoms see below will prompt mid-stream clean catch specimen for urinalysis and urine culture During this period patients will be closely observed for infectious complication--ie symptomatic urinary tract infection defined as presence of bacteruria 5k colony forming units with any of the following fever 38 C malodorous urine dysuria urinary frequency urinary urgency lower abdominal discomfort back pain gross hematuria Patients will be evaluated at 8 weeks for re-assessment in the clinic with a renal bladder ultrasound performed at 6 weeks which is the routine post-operative care
